Patented Apr. 1, 1930 PATENT OFFICE EDWARDYF. MCI-HIGH, OF KINGSTON, PENNSYLVANIA ADJUSTABLE SILL R JAMB COVERING Application filed July 24, 1928. Serial No. 294,997.

This invention relates to an adjustable sill or amb covering designed primarily for use in connection with ventilating sashes employed upon store fronts, etc., for supporting plate glass windows, but it is to be understood that a sill or jamb covering in accordance with this invention may be employed for any purposes for which it is found applicable, and the invention has for its object to provide, in a manner as hereinafter set forth an adjustable sill or jamb covering of variable dimensions for eliminating entirely, precise dimensions, which are necessarywith all other'store front'settings, particularly as the covering, in accordance with this invention functions without interfering with the function of the sash. or in other words, the sash operates independently, and the cover ing adjusts itself to whatever dimensions the carpenter'might have laid out.

Heretofore, it was necessary that such dimensions be precise, because of the fact that the coverings, extended clean back to the M backing stops, and the back member of the sash sets against theupturned lip or flange of the covering. To be more explicit, this upturned lip or flange of the covering would be positioned between the backing stop and lower'part of the inner sash member.

However. an adjustable covering in accordance with this invention eliminates this condition, entirely, as the covering has no relation to the backing stop whatsoever, being variable from the front leg, of the inner sash member, to the rear leg, of the inner sash-member, and between both legs thereof.

A further object of the invention is to provide, in a manner as hereinafter set forth, an

adjustable sill or jamb covering of variable dimensions to provide a seal tight joint, at all dimensions, thereby preventing leakage or filtration. Further objects of the invention are to pro.-

vide, in a manner as hereinafter set forth, an adjustable sill or j amb covering which is simple in its construction and arrangement, strong, durable, thoroughly .efiicient in its use, adjustable to all dimensions with respect to the sill or jamb, conveniently installed,

and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claim hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughoutthe several views Figure 1 is a vertical sectional view of a sill or jamb covering in accordance with this invention showing the adaptation therewith in connection with a head jamb, sash and glass and with the covering illustrated adjustable to its extreme outward limit.

Figure 2 is a vertical sectional view of a modified form of covering showing the adaptation thereof with respect to a center jamb, a pair of sashes and a-pair of glasses and with the covering adjustable to its e} xtreme outer limit.

Figure l is a vertical sectional view of the form of covering shown in Figure 3 and illustrating the adaptation of the covering with respect to the sill, sash and glass and further illustrating in full lines the adjustment of the covering to its extreme inner limit and in dotted lines the position of the covering when shifted to outer adjustments thereof.

Figure 5 is a perspective view illustrating a back member of a sash and the form of covering shown in Figure 2 and with the covering and back member in disassembled position.

upper jamb having secured to the rear portion of its lower face a depending backing stop 2.

In Figure 2 of the drawings 3 indicates a center jamb having secured to the rear portion of its upper face a. backing stop 4 and to the rear portion of its lower face a backing stop In Figure 3 of the drawings 6 indicates a sill having secured to the rear portion of its upper face a backing stop 7.

In Figure 4 of the drawings 7 indicates a sill of less width than the sill 6 and which has secured to the rear portion of its upper face a backing stop 8.

In Figures 1 to 4 of the drawings the sash includes an inner member, termed a back member and which with reference to Figure includes a back part 9 provided at one end with av forwardly directed flange consisting of an inclined inner part 10, a flat part 11 and a lip 12 disposed at right angles to the part 11. Projecting forwardly from the part 9 and positioned above the bottom thereof is a horizontally disposed part 13 which constitutes a cushion and which has its rear integral with a leg 14 which merges into the part 9. The part 13 at its forward side terminates in a flange consisting of a horizontally disposed part- 15 and a vertical part 16 which is disposed at right angles with respect to the part 15. The part 151's positioned against the part 13. In. Figure 2 a pair of l aek members are employed, one positioned against the upper and the other against the lower face of the center jamb 3 and the said back mem bers employed in Figure 2 are oppositely disposed with respect to each other. In Figure 1 the back member is oppositely disposed with respect to the back member shown in Figures 3 and 4. The part 16 forms the forward leg of the backing member and the leg 14 is the rear leg of the latter.

With reference to Figures 1 to 4, the sash further includes an outer moulding 17 formed with a rearwardly directed flange 18. The front moulding further includes a vertical flange 19 which opposes the vertical part ii-Z of the back member. In Figure 2 a pair of front mouldings are employed and which are oppositely disposed with respect to each other. The front moulding 17 in Figure 1 is oppositely disposed with respect to the front mouldings shown in Figures 3 and 4. The front moulding is termed the outer sash member. The plate glass 20 is positioned between the parts 12 and 19 of the sash or in other words, clamped between said parts. Holdfast devices 522 secure the outer sash member or front moulding in position. Holdfast dc vices 22 extend through the sash and engage in the back stop. In Figures 8 and 4 the setting block 23 is mounted upon the part 18 of the back member and carries a cushioning element 24 for the glass 20. The setting block is mounted upon the part 13 of the back meniher and said part 13 constitutes a cushion. The parts 14 and 16 of the back member provide supporting legs for the cushioning part 13, and said legs oppose each other, but are spaced an appropriate distance from each other.

The covering shown in Figure 1V is employed in connection with a head jamb 1 and includes a vertical part 38 and a horizontally disposed part 39 projecting rearwardly from the lower end of part 38 and arranged against the lower face of jamb 1 forwardly of and spaced from the part 9 of the backing member. The part 38 is slightly less in height than and is positioned against the front of the ja-mb 1. The part 39 at its inner end is formed with a depending flange or lip 40 which is positioned between the parts 14 and 16 of the backing member. The flange 18 of the front moulding 17 opposes the part 39 of the covering. The flange 40 is variably positioned between the parts 14 and 16 of the backing member depending upon the width of the amb 1, or rather that portion of the jamb extending from the backing stop 2.

When the covering shown in Figure 1 is mountedin position the flange 40 prevents the shifting of the covering from off the amb due to the fact that on the outward shift of the covering, the flange 40 will abut the part 16 of the backing member, and the latter is interposed between the flange 40 and the inner side edge of flange 18 of the front moulding 17. A top moulding 42 opposes the upper portion of the part 38 of the coverin The modified form of covering shown in Figure 2 is employed for use in connection with the central jamb 3, and it includes a vertical part 47 for positioning against the front of the jamb 3, an upper part 48 mounted against the forward portion of the top of j amb 3 and a lower part 49 arranged against the forward part of the bottom of the jamb 3. The parts 48 and 49 extend rearwardly from the top and bottom respectively of the part 47 of the covering. The rear of parts 48 and 49 are provided respectively with upwardly and downwardly directed vertical flanges 50, 51. The widths of the parts 48. 49 are the same. The covering shown in Figure 2 is adjusted to the outward limit thereof. The flanges 50, 51 are positioned in the same manner as the flange 40 with respect to the sashes arranged above and below the jamb member 3. The flanges 1.8 of the sashes 17 oppose the outer faces of the parts 48, 49 of the covering. The flanges 50, 51 of the covering coact with the parts 16 of the back mem bers to prevent the covering from being shifted off the jamb. The parts 16 of the back members are interposed between the inner edges of the flanges 18 and the flanges 50, 51.

The form of covering shown in Figures 3 and 4 comprises a vertical part 62 for positioning against the front of the sill 6 or 7.

.- sill 6 or 7. The coverin further includes a D rearwardly extending, horizontal part 641 at the lower end of the part 61. The part 61 is of greater height than the front of the sill 6 or T and depends below the bottom of the latter. The part 64 has its inner por-- tion upset, as at 65 and abuts the lower face of a sill 6 or 7. The part- 64 atits rear is formed with a depending, vertically disposed flange 66 which abuts a support 67 for the sill. The part 64 constitutes what may be termed a resilient latch.

In Figure 3 the covering is shown adjusted to its limit of outward movement and the part 63 of the covering at its rear is formed with a vertically disposed flange 68 between which and the inner edge of the flange 18 of the sash 17 is arranged the part 16 of a back member. The flange 68 is arranged with respect to the back member in the same manner as the t flanges 40, 50 and 51 heretofore referred to.

The flange 18 of the sash opposes the outer face of the part 63 of the covering.

In Figure 4 the covering is referred to generally at 68 and is shown in full lines adjusted to the limit of its inward movement with respect to the sill 7 but if the sill is wider than as shown in full lines, and extends to the position indicated at 70, the covering 68 can be adjusted to properly enclose the J forward portion of the sill. and if the latter extends to the position indicated at 71 the covering can be adjusted so that it will properly protect the forward portion of the sill. The covering 68 is provided for variable dimensions of sills or jambs.

The covering can be of the form shown in Figures 3, 4 and 6 or as shown in Figure 2, or as shown in Figure 1.

It is thought the many advantages of a sill or jamb covering of variable dimensions can be readily understood, since it eliminates, entirely, precise dimensions, which are necessary with all other store front fittings, particularly since the adjustable covering, in

1 accordance with this invention, functions without interfering with the function of the sash. The sash operates independently, and the covering adjusts itself to whatever dimensions the carpenter might have laid out. A covering in accordance with this invention has no relation to the backing stop whatsoever, being variable from the front leg, of the innersash member, to the rear leg of the inner sash member, and between both legs thereof. Further the covering provides a seal-tight joint, at all dimensions, thereby preventing leakage or filtration.

Although the preferred embodiment of the invention is asillustrated and described, yet it is to be understood that changes in the details of construction can be had which fall within the scope of the invention as claimed.

lVhat I claim is: A covering for sills or jambs of varying dimensions comprising a unitary imperforate body formed of a vertical part and a pair of horizontal parts extending at right angles to the ends of the vertical part, each of said horizontal parts having the free end thereof formed with a vertically extending right angularly disposed flange for slidably connecting said body to a pair of metallic sashes connected to a sill or jamb whereby said body can be adjusted to cover sills or jambs of varying dimensions.

In testimony whereof, I afiix my signature hereto.
